It's the same capability--being able to drag defenses and always fall forward for extra yards, even when your blockers are getting overwhelmed down after down.

Over the years, a very consistent pattern has been our inability to run the ball against the better defenses we've faced. That goes a long ways towards explaining why we've lost so many of those games. But not when Unga played. I can't look up the stats at the moment, but I would have to say that Harvey has more 100 yard games against BCS teams (including Utah and TCU) than any other BYU RB, at least in a very long time. That was what made him special to me.
